A wave guide probe for use with direct-read tank level gages to provide electric signal output is disclosed. The apparatus comprises a translucent tube, a wave guide probe, and an electronics assembly. The translucent tube is for containing a fluid interface. The wave guide probe is positioned in the translucent tube. The electronics assembly is operably associated with the wave guide probe for actuating the wave guide probe and producing an electrical output signal representative of a location of the fluid interface in the translucent tube. The apparatus provides both electronic and optical level indications and is well suited for tank applications.
